Application filed Kay 27, 1911-. Serial No. 629,851.

To all whom it may concern Be it known thatI REBECCA M. DON0- rips, acitizen of the lJnited States, and aresident of Oakland, in the county of Alamay be used twice before its efliciency is destroyed.

Heretofore, as far as I am aware, all envelops which have been 'used for return purposes have been formed of two or more pieces of stock, fastened together, which renders the envelop more expensive than the common method of inclosing an addressed envelop for the reply.

By the use of my invention a return reply envelop is formed which has the a pearance of an ordinary envelop and whic is only slightly more expensive than the ordinary envelop. I/

With these and other. objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, here inafter fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claim, it being understood that various changes in the form, proportions, size, material and minor de-' tails of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

The following description explains the nature of my said invention and the manner in whichl proceed to 3. ply the same in theproduction of an enve op, reference being had to the accompanylng drawings in which Figure l is a view of the blank from which the envelop is formed, the senders card and return address being printed thereon in their proper places. The lines crossing the blank indicate the lines of fold. Fig. 2 is a view' of a sealed envelop, part of the front face being torn away to disclose the position of the return address flap.

'Fig. 3 is a view of the back of an envelo after it has been opened and the return a dress flap withdrawn therefrom. Fig. 4 is a View of the envelop as sealed for the return reply. Figs. 5 and 6 are exaggerated cross sections through theenvelop as'originally mailed and as sealed for the return reply, the envelo being shown empty.

The blank is ormed with the customary body or face 2, the side flaps 3, and the seal flap 4. The back flap 5 is made rectangular in shape and of less height than the face 2 so that when the blank is folded and the envelop sealed, the upper edge of the back flap will lie below and be spaced apartfrom the upper edge of the envelop. Attached to theback-fiap 5 and formed integrally therewith is the return address flap 6. This flap- 6 is of slightly less area than the face 2, is not greater 1n height than the back flap 5, and is provided with rounded corners 7, for reasons as will hereinafter appear. Upon this flap 6 is printed the address to which the reply is to be sent. In folding the blank to complete the envelop the reply address flap 6, folds into the interior of the envelop and is preferably folded on itself so that the edge 8 lies adjacent the opening in the envelop, and below the upper edge of the face 2, as shown in Fig. 5.

When the envelop has been sealed, it must be opened along the upper edge in order that i the reply address flap may be withdrawn and used. This fact niust be called to the attention of the person opening the envelop, or he may open it on the end and defeat the purpose of the invention, as shown in the present embodiment. The persons attention may be called to this fact by printinga notice on the face of the envelop 'adjacent the upper edge, or by running lines of perforations 9 adjacent the edge or by other similar means.

After the envelop has been opened along the upper edge, the reply address flap 6 is withdrawn, the corners 7 thereof being rounded to facilitate its removal. This flap, which is integral with the back of the envelop is now folded over the front and sealed thereto in the usual manner by means of the gummed surface 12. The old address has therefore been covered and the envelop in the drawings, sothat'the person repl 'ng will place the stamp on the envelop a ong the lower edge as now shown, attaching the stamp partly to the reply flap 6 and partly to the face 2, thereb efiectively sealing the envelop by means 0 the stamp and making it more dlfiicult for an unlicensed person to open.

In the envelope shown in Figs. 5 and 6, the envelop has been opened by tearing along the lines of perforation so that the return envelop 'is slightly smaller than the original, but where such perforations are not employed the return envelop will be of the same size as the original.

The envelop may also be used for inclosing mail matter ,not sealed from inspection by folding the seal flap into the envelop in stead of sealing it to the back flap.

flap comprising an extension of the back single sheet comprising a ody ortion, end flaps, a seal flap, a tack flap 0 less height than the body portion, 'andaj return refiwly.

being not greater in height than the height of the bat: i from the" body ortion, said return reply flap folded upon itself along its longitudinal center line and being arrangedwithin the envelop so that the free edge thereof lies adjacent the edge of the body portion from which the seal ap extends.
